Specification of Letters Patent.

Patented July 9, 1907,

Application filed October 15,1906. Serial No- 339,067.

' use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates to rolling-mills and has for its object a guiding device which is particularly adapted for small and medium sized mills with highspeed rollers and is for use in rolling raw material on rollers without grooves. In this manner the necessity of having variously grooved rollers for the separate profiles is avoided. Now the use of lateral guides for this purpose is already known. The same were arranged either in front or in front and behind the rollers or extended through the rollers. They had the disadvantage however that they were not at all adjustable, or only adjustable with a proportionately large expenditure of time. Therefore it very frequently happened that if the head of the material to be rolled was somewhat torn open or cracked and thickened, or was bent by falling on the ground, this head must be first cut off, before it could be put into the guide.

Moreover the material to be rolled frequently cooled down in such a way that it must be heated afresh or be cut up for scrap. Also it frequently happened that the end of the bar of iron which was rolled through remained stuck in the second rear guide, as soon as it had passed the rollers.

In accordance with the present invention only one guiding device is employed which extends through between the rollers and consists of two cheeks or sidebeams arranged in a frame of which the one is fixed and the other is mounted revoluble on a vertical axle which is situated a little in front of. the narrowest place between the two rollers, namely near the point where the rollers seize the material to be rolled. By the one check swinging round its pivot, the guiding device opens in inserting and withdrawing the bar in front or behind the rollers, and considerably facilitates the insertion and also the withdrawal of the material. But as soon as the material to be rolled has been seized by the rollers the movable cheek adjusts itself automatically parallel to the fixed one. The movable cheek rotates round a pin which is fastened in a slide guided by means of grooves in a frame, said slide being easily displace-able and exchangeable, so that the pivot of the cheek can be displaced by moving the slide nearer to or furtl ierfrom the rollers, and moreover another cheek can be inserted for altering the groove. It is evident that by this arrangement of the guiding device a jamming of the material to be rolled when the same is inserted is avoided, as also when is withdrawn, even if the ends are thickenedl The setting of the cheeks takes place automatically and without the aid of special superintending workman, and indeed in the same moment in which the material to be rolled is seized by the rollers, so that the rolled bar is of absolutely uniform condition from the beginning to the end.

More particularly the present invention consists in a guiding device for finishingrolls, and in order that the details of construction may be more clearly understood, reference is made to the accompanying drawing, in Which:

Figure l. is a side elevation of a section of the guiding device in one form given by way of example for a roll ing mill for stamping or compressingz-Fig 2 is a plan; Fig. 3 is a front elevation; Fig. 4 shows the frame for the guides in side elevation, and Fig. 5 is a section through the movable cheek.

Similar letters of reference refer to similar parts in all views.

The material I) to be rolled is guided on the way through the rollers a and a between the guides or checks or side-beams e and Both the latter are mounted. in the frame 0 which is fastened in optional manner to the frame (1 of the mill. The movable guid ing cheek f rotates round a pin h which is fastened in the slide 9 (Figs. 3 and 5), the latter being held by the set-screw i and guided in the grooves k, k of the frame 0. The fixed guiding cheek is adjusted by the laterally arranged set-screws Z, Z 1 l and Z. It is beveled at both sides or only at the under side, and is supported from below by the inclined plane in of the frame 0 and held in its position from above by the setscrews n, n, so that a yielding of this check is prevented.

In inserting the material to be rolled the front end of the easily revoluble check is in the first place displaced laterally corresponding to the dotand-dash lines in the drawing. But as soon as the material is seized by the rollers and pressed through the passage which has become narrower behind the pivot of the cheek, the rear end of the cheek f is pressed to the side, but the front end is simultaneously closed to such an extent that both cheeks are parallel to one onother and form an exact guide for the material to be rolled. When the last end of the material is through the rollers and consequently is past the pivot, the rear end of the movable cheek shifts to the side and the rolled material can be withdrawn without being jammed.

In order to vary the cross-section of the passage the fixed cheek is adjusted by means of the screws 1 and n, and the movable cheek together with the slide is exchanged for another. I

The guiding device'is not only able to be employed for upsetting mills, but also for other optional mills.

What We claim as our invention and desire to secure by Letters Patent is:

1. The combination in a rolling mill with a pair of rolls and a pass between the rolls, of a guide frame, guide mem hers mounted on said frame and extending through the pass, one of said guide members pivotally mounted between its ends on said frame at a point near the nipping point of said rolls.

2. The combination in a rolling mill with a pair of rolls and a pass between the rolls, of a guide frame, guide members mounted on said frame and extending through the pass, one of said guide members adjustable to and from the other guide members, and the other guide member pivotally mounted between its ends on said guide frame, an exchangeable pivoted guide (1),

l l l frame near the nipping point of the rolls to move as the stock is fed between them and through the pass.

3. A guide device for rolling mills comprising a guide frame, a guide, means adapted to fix said guide in said a slide (g), means adapted to fix said slide in said frame, and a stud (h) mounted vertically on said slide and supporting said guide (f), said slide being normally fixed to said frame.

In testimony that we claimthe foregoing as our invention, scribing witnesses.
